Pop Start LC R1200RT?

Has anyone ever needed to pop start the LC RT or even tried? I was just wondering if it can be done on modern motorcycles like the RT if a battery drains too much.

Don't think so because of the fuel injection.

Re: Pop Start LC R1200RT?

Yep! Have done it once. Stopped at a service station to fuel the bike up. Went to start it, dash lit up, hit the starter, and dash display died. Release the starter button and dash came back up again. Luckily the servo was situated on a slight hill. Was able to roll down the hill in second gear and pop the clutch at the same time as bouncing on the seat and the engine fired up. Got home and checked out the problem. Battery had likely dropped a cell. New battery the following day and all good.

That was because you still had fuel pressure built up. That will not work unless the bad battery has enough juice to get the fuel pump running for a cold start.

^ true. There must be enough power in the battery for the ignition/fuel circuits to be functional.

I never try on the newer bikes, but I have done it on 11 and 1150 countless times, they actually start after a few feet (much easier than a "Normal" bike)

Yes I got in a dead battery situation while traveling...left the key on...oops...and even loaded with travel gear with a dude helping to push on blacktop in a high gear....could not make it happen....seemed like it just slid the tire and would never turn over...so a jump box to the rescue...2014 RT

Like with any bike you need to jump in the seat at the exact second and let the clutch go "Just Right"

It takes practice but i can be done..

It also helps if you try it in 2nd or 3rd rather than 1st gear.

That's why it's called "bump-start", in the old days. That's how racer started their bikes at the beginning of the race, back before we had gone soft and have electric starter on our bikes!

. . . . or higher gear, but you have to be quick with the clutch.

i never had a "Total loss"no means to start bike but a few times my GS had weak batteries, and I start them on my own just running on flat ground then JUMPING on the seat at the exact moment and Yes second gear is much better, on first will skid for sure

I guess the torque works both ways..

I tried with a battery with 3 volts in it (didn't know it at the time) with someone pushing me and it was a nogo. Ran okay on the alternator okay but once I turned it off that was it. I would assume if you could get the alternator to generate a bit of power it would go.
However it is a big beast to push start unless you have a good downhill slope.

Of course those older race bikes were generally much lighter and low compression 2-strokes.

Ahhhhh....you are far too young!!!


Go back further in time, to when two-stroke were dirty words and engines were cast-iron and not aluminum alloy. My old Norton would have been the lightest, with it's world famous "featherbed frame", and yet in it's racing set-up it would weigh in at over 400 pounds wet. Compression ratio? Try 12 : 1, just like the hexhead and camhead RTs. The only place where 2-strokes were favored, back then, were in scrambling, but that's where I had used the old BSA 500cc single, 4-strokes over the much lighter 2-stroke Greeves and other favorites of the time.


BTW, there is a proper technique to bump-starting. The reason that it's called bump-start is that you deliberately bump hard onto your seat and at the same time drop the clutch. The bump gives added traction to the rear wheel, and so it's important that you drop the clutch at that precise point, and be ready to pull the clutch back in again as soon as the engine catches, since you will be doing this in the higher gear.

That's why I carry a jump starter battery pack in my tank bag. The one I have is about the size of my iphone but slightly thicker. I've used it to start cars, trucks and my '13RT on a cold morning in Colorado a couple of weeks ago - fired it right up. Bought it on Amazon a few years ago for less than $50.00. Gives you peace-of-mind when you have an old battery.

Yep a big +1. I do the same. I can't believe such a tiny thing can start big engines. I used mine on a few bikes and a Z3 BMW. Gobsmacked!

I carry an XP-1 Antigravity Battery on the bike. Odd this comes up today. I just had to use it on my 2000 Silverado [LS1]. It's been parked a while. Brought it home last night and parked in the driveway. This morning "click, click". Connceted the XP-1, turn it on, wait a minute - starts right up.
